The Patented Drainage Plane and Metal Lath System for Adhered Masonry Veneers Designed for use with stucco, thin brick, stone and other types of adhered masonry LathNet is a metal lath and drainage plane system that provides a continuous drainage plane between the lath and weather resistant barrier. The Masonry Advisory Council recommends that in exterior adhered masonry wall systems, a drainage mat be installed to drain any water that has penetrated to the flashing. A galvanized expanded metal lath, or diamond mesh, should be attached atop the drainage mat.
